IMO it gets better. Many disagree. Theres only 8 per season so it doesn't get stale or anything.

I was gonna ask if it's still worth watching - I've only seen the first season and it dragged on a bit, IMO. Do the later season/s have more going on? I just thought the first one didn't have much story, it could have been done as a three parter.

(though I might watch the Swedish version, as it has that fit guy)
